裝置，係使用記錄有聲音或影像之小型碟片（下稱光碟>、 及爲了使其再生，乃使用了光碟驅動之再生機能，在# $ % 用碟片上，對設置之分析對象作追踪循跡（trace)，医I ^ & 得影像者。 一般光碟驅動，係詳如第9圖所示之構成。 光碟1 0 1係以碟片馬達1 〇 2依箭頭方向C作回轉驅動。 將檢出光照射於光碟1 0 1，把反射光檢出之拾波器（p i c k up ’或稱拾光器）1 0 3 ’係在光碟1 0 1之軸徑方向（箭頭A方向） 移動’縱向進給馬達（t r a n s v e r s e m 〇 t 〇 r) 1 0 4係驅動使螺紋 _ 軸1 0 5轉動。 該縱向進給馬達104及該碟片馬達1〇2係基於拾波器 1 0 3之再生輸出、藉伺服控制電路6作以下方式之運轉 ’伺服控制電路1 0 6係基於拾波器1 〇 3之再生輸出而追隨 形成有凹机（pit)或紋道（gro〇ve)等之軌道，依循跡（trace) 之方法將縱向進給馬達i 04驅動，同時，檢出記錄在光碟 1 0 1上之位址資訊’對碟片馬達2以一定之線性速度加 -6- 200306413 以驅動（CLV控制）。 又，記錄在該碟片中之聲音信號、影像信號等資料，係 使拾波器1 〇 3之再生輸出在再生處理裝置1 0 7中加以處理 ，並成再生輸出。 另一方面，如係分析裝置之狀況，其方塊與上述光碟之 驅動大約相同。分析裝置之狀況爲，如第1 0圖所示，係將 檢體暨配合檢查項目之試藥兩者的混合物作爲分析對象B 另外的設置（set)在軌道la上，分析裝置狀況中之伺服控 制電路1 0 6及再生處理裝置1 0 7，係以下述方式取得光碟· 1 0 1上、該分析對象B之部分的影像。此處，軌道1 〇 1 a上 之箭頭方向係表示來自拾波器1 〇 3之檢出光的循跡方向。 又，作爲位址資訊、形成於光碟中之凹坑、紋道等之上 的時間資訊，雖係作爲分析用之碟片狀況，因仍係沿用習 知記錄有聲音、影像之光碟規格，故省略其詳細說明。茲 舉兩個具體代表例，即：Compact Disc System Despription (通稱：Red book 規格）；及 Compact Disc Recordable System Description(通稱：Orange book 基準）。 _ 伺服控制電路1 0 6所控制拾波器1 〇 3之雷射照射點，係 循跡於光碟1 0 1之螺旋狀軌道1 〇 1 a。軌道1 0 1 a之命距 (p i t c h )，如係D 1· a n g e b ο 〇 k基準之光碟時’爲1 · 6 μ m，拾 波器1 〇 3在光碟1 0 1的一個回轉中係依序的以1、2、3〜 、8、…作循跡。 總之，作爲分析裝置之動作，係使分析對象B之部分及 該軌道1 0 1 a之部分交互的通過而循跡之。分析裝置狀況之 200306413 再生處理裝置1 〇 7係，僅抽出循跡所得分析對象B之部分 資料、藉資料之再構築而實施影像或形狀計數。 分析裝置之狀況中，實施之構成可爲：使光碟再生，依 一般性的光碟驅動方式，將來自光碟之反射光檢出而予處 理之型式；或可爲：將來自光碟之透過光予以檢出作處理 之型式；任何一種型式均可。 如上述，作爲位址之資訊的絕對時間係刻於CD及DVD 等碟片上。該時間資訊之構成有分、秒、幀（frame)等，而 1秒之構成幀數爲7 5幀。 此種時間資訊之記錄方式可分成兩大類，其一爲：藉將 E F Μ等之凹坑長度加以改變而記錄資料之方式；另一爲： 於記錄系列之碟片上，將紋路作F Μ變調而成蛇行之記錄 方式。 依此種光碟使用之一般性時間資訊，在分析裝置中，無 論係施作影像信號之組立處理或形狀計數，均不足以奢望 提高其分析精度，理由如下述。 光碟驅動裝置及分析裝置之任何一種，爲了檢索光碟 1 〇 1上之任意位置，係利用記錄於光碟上既存之位址資訊 。但是，自位址資料所獲得之最小單位距離，以一般光碟 系列爲例，其1秒係由7 5幀開始計算，而碟片之線速度係 大於1 .2m/l幀〜1 .5m/l幀，故無法爲最小之120(cm)T75 (幀）=1 .6(cm)/l幀。亦即，其精度爲最小單位之1幀係每 隔 1 6 m m者 。 血液檢查之分析裝置狀況中，依目前狀況，儘管亦要求 200306413 在光碟1 0 1上約爲5 m m四方之小區域上，須可檢出約1 0 μ m 物件之精度，雖遂行了：將追隨軌道之拾波器1 〇 3在時系 列上所讀取之該分析對象Β的影像實行影像處理，獲得如 第1 1 ( b )圖所示正確之讀取影像結果，而再生處理裝置（1 0 7) 則把該位址資訊在基準上行影像處理；等方式，惟仍無法 獲致如第1 1 ( a)圖所示讀取之影像。 詳言之，如第1 1 ( a)圖所示，再生後之影像爲，不吻合循 沿光碟1 〇 1回轉方向C位置所產生之影像係停止形成者， 故偏離了分析血液等所要求之精度値，可了解的是，此種 過於粗糙之結果實無法加以使用之。 (三）發明內容： 本發明之目的，係提供一種分析裝置及其使用之特別的 分析用碟片，可滿足血液分析等之高精度要求，並可實現 形狀分析者。 發明之開示： 本發明並非係，將追隨軌道之拾波器在時系列上所讀取 之信號刻於光碟上，利用依此所成之位址資訊作爲影像而 予組立之分析裝置，依本發明，係將其他之事項予以整列 在基準上，以實行影像處理，爲一種可遂行取得高精度影 像或形狀計數之分析裝置者。 本發明第一實施例係，將檢出光照射於一部分配置有分 析對象之分析用光碟上，以讀取分析對象狀態之分析裝置 者。此種分析裝置係設有：拾波器；對配置有分析對象之 讀取區域、於回轉方向前後位置之至少一位置上，可設置 200306413 (set)以記錄有經過讀取位置軸徑方向區間之記號的分析用 碟片，而可檢出來自配置於所設置分析用碟片上，分析對 象之檢出光及該記號。及影像處理裝置；將追隨軌道之拾 波器在時間系列上所讀取之分析對象及記號之讀取信號兩 者，把記號之位置整列於基準之時間軸，以實行影像處理 而取得分析對象之影像或形狀計數；等爲特徵者。 而依本發明分析用碟片之特徵係，可令凹坑或紋道 (groove)再生，具有爲了控制碟片回轉之資料領域，及可 對所配置之分析對象讀取之區域（area)，等之一種分析用 碟片者。對配置有分析對象之分析區域之回轉方向、於回 轉前後位置之至少一位置上，係記餘有經過該讀取區域軸 徑方向之區間的記號者。 又，依本發明分析用碟片之特徵，尙爲該記號可由凹坑 、或紋道、或紋間平面（land)、或印刷、或非爲鏡面或形 狀異型等不同方式形成者。 又，依本發明分析用碟片之特徵，於記號之凹坑、或紋 道或紋間平面上，係設以不同於資料領域之特定圖型 (pattern)者 。 又，依本發明分析用碟片之特徵，係使記號之特定圖型 對應於配置分析對象之複數個讀取區域而有所不同者。 又，依本發明分析用碟片之特徵，係使記號之特定圖型 對應於配置讀取區域之分析對象種類而有所不同者。 其次，本發明第二實施例之分析裝置，其特徵爲該分析 裝置係設有：拾波器；在設置之分析用碟片上、對配置有 -10- 200306413 分析對象之讀取區域、於回轉方向之前後位置的至少一個 位置處，對以對應於分析對象種類而成不同之特定圖型之 記號。因之，可檢出來自分析對象之檢出光及記號。及影 像處理裝置；將追隨軌道之拾波器在時間系列上讀取之分 析對象及記號之讀取信號兩者，把記號之位置整列於基準 之時間軸，而實行影像處理以取得該分析對象之影像或形 狀計數，同時，令影像處理之結果基於特定圖型而附於所 對應配置在讀取區域分析對象之種類以作管理者。 其次，依本發明分析裝置第三實施例之特徵爲該分析裝 置係設有：拾波器；在設置之分析用碟片上、對配置有分 析對象之讀取區域、於回轉方向之前後位置的至少一個位 置處，設以對應於分析對象種類而成不同之特定圖型之記 號。因之，可檢出來自分析對象之檢出光及記號。及影像 處理裝置；將追隨軌道之拾波器在時間系列上讀取之分析 對象及記號之讀取信號兩者，把記號之位置整列於基準之 時間軸，而實行影像處理以取得該分析對象之影像或形狀 計數，同時，令影像處理之結果基於特定圖型而附於所對 應配置在讀取區域分析對象之種類以作管理者。 (四）實施方式： 以下，基於第1〜8圖說明本發明各種實施例。 (第一實施例）： 第1圖爲本發明之分析裝置，其中以微電腦構成之再生 處理裝置1 0 7、及取代光碟1 0 1者爲使用作分析之分析用 碟片108兩者與習用者不同。 -11- 200306413 分析用碟片1 〇 8，係如第2圖所示，於光碟！ 〇丨上設置 (s e t)有作爲分析對象B之檢體、與配合檢查項目之試藥兩 者之混合物，對配置有該分析對象B之讀取區域之回轉方 向C，僅於其正前方位置處，記錄以經過該讀取區域軸徑 方向（箭頭A方向）之區間的記號i10F。第2圖所示者，分 析用碟片108上係設有兩個分析對象B，於各分析對象之 正前方位置處，形成有該記號1 1 0 F。 於分析用碟片1 〇 8中，對於分析對象b之位置及分析用 碟片等之記號1 1 〇 F，則如第5圖所示之構成。 如第5圖所示，分析對象B係設於分析用碟片1 〇 8之表 面l〇8a，與軌道101a之間。記號ll〇F係在光碟101之裏 面以印墨（i n k) 1 1 1作帶狀之印刷而成。在第5 (a )圖中，1 1 2 a 係以鏡面加工形成於軌道1 0 1 a之凹坑或紋道。1 1 2 b則爲 以鏡面加工形成於軌道1 0 1 a之紋間平面（1 a n d)。 又，如第5 ( a)圖假想線所示之分析對象B，係與設在分 析用碟片1 0 8之裏面1 〇 8 b及軌道1 0 1 a之間之構成狀況相 同。 拾波器103係循跡（trace)於分析用碟片108之螺旋狀的 該軌道1 0 1 a，伺服控制電路1 〇 6係基於拾波器1 0 3之再生 輸出而追隨形於凹坑或紋道等之軌道1 0 1 a，以循跡之方式 驅動縱向進給馬達（t r a n v e r s e m 〇 t 〇 r) 1 0 4，同時，檢出軌道 1 〇 1 a上記錄之位址資訊，以一定之線速度驅動碟片馬達 1 02(CLV 控制）。 作影像處理裝置之再生處理裝置1 〇 7係如下述之構成。 -12- 200306413 再生處理裝置1 〇 7係，首先，將拾波器1 〇 3讀取在時間 系列上的影像資料作爲循跡資料而蓄積於記憶體1 1 3中。 此處，對兩個分析對象Β因均係作相同之處理，故只舉一 個分析對象Β以第5圖說明處理之內容。 第4(a)圖係，光碟101 —個回轉，拾波器103自圖之上 方往下，依次由第1至第9軌道作循跡而蓄積於記憶體11 3 之循跡資料者。此處爲，第2〜第8軌道之上，位置有分 析對象Β之一部分，V 2〜V 8爲分析對象Β之分解圖像資 料。S 1〜S 9爲用以對讀取記號1 1 OF後之各軌道位罝每個 鲁 位置觸發的信號。 由檢出自記憶體1 1 3所讀出循跡資料中之觸發信號的觸 發電路1 1 4，及基於該檢出電路1 1 4之檢出輸出、可補正 軌道每個循跡資料之時間軸的切換電路1 1 5，兩者所構成 之第1處理部1 1 6係，使朝向自記憶體1 1 3讀出之循跡資 料後段的輸出時序（timing)作適當的延遲，而如第4(b)圖 所示各觸發信號S 1〜S 9之位置爲相一致之方式，使各軌 道每個循跡之時間作移動而輸出圖像資料D。更具體言之 ，該第4(a)、（b)圖之狀況中，爲了與觸發信號S2之位置 相一致，乃使觸發信號S 1、S 3〜S 9之輸出延後者。 依此種方式，將記號Π 0F補正在基準之時間軸後各軌道 之循跡資料係，蓄積於第2處理部1 1 7後，作爲再生影像 輸出而輸出之。又，倘非僅取得該分析對象之影像而尙須 形狀計數（count)時，亦可實行單位面積之計數處理。 依此方式，藉由將該記號1 1 〇 F之位置予以整列在基準之 -13- 200306413 時間軸，則依習用方式，將位址資訊整列於基準上之時間 軸，亦可獲得高精度之畫像資料。 (第二實施例） 第6圖爲第二實施例之分析用碟片。 在第一實施例中，係僅在對配置有分析對象B讀取區域 、於回轉方向之正前方配置而已，而如第6圖所示之本例 ，係於該分析對象B之正後方，亦同樣的設以一個記號Π 0B。 於未設記號1 1 〇 B之第一實施例狀況中，在到達次一個 讀取記號1 1 〇 F前之間所經過者係作爲一個軌道之循跡資 料記錄於記憶體1 1 3中，如是，倘使用在分析對象B之正 後方亦設以記號11 〇 F之分析用碟片時，可令分析裝置之再 生處理裝置1 〇 7藉由：自記號1 1 〇 F讀取之後至讀取記號 1 1 0B爲止之循跡資料蓄積於第1記憶體1 1 3，的構成，而 蓄積與分析對象B無關係區間之循跡資料，可毋須施作處 理，因而可達成所預期之高效率資料處理。 (第三實施例） 第一實施例之分析裝置，其再生處理裝置之構成係讀取 記號11 〇 F後之觸發信號S 1〜S 9，將時間軸補正以成一致 ，倘未設記號1 1 〇 F時，則僅能在該分析對象Β之正後方 使用設有該記號1 1 〇 Β之分析用碟片1 0 8，而可令分析裝置 之再生處理裝置1 〇 7藉由：使讀取記號1 1 0Β之觸發信號 作一致性之時間軸補正的構成，仍可達成與第一實施例相 同之預期效果。 又，於第一、二、三實施例中，第2圖或第6圖所示之 -14- 200306413 記號1 1 F、1 1 0 B之設置係由碟片之中心而偏置（〇 f f s e t)，並 與分析對象B之讀取部分相平行。此狀況中，自記號至檢 體之距離，因和碟片上之內周與外周相差不多，故如對較 大檢體（數mm以上）作影像化時，具有不失真且無瑕症顯 像之優點。 (第四實施例） 上述各實施例之分析用碟片1 〇 8、記號1 1 0 F、記號1 1 0 F 與記號110B、記號110B等任何一者均可如第5(a)圖所示 以印刷之方式構成之，而如第5 (b)圖所示方式，在鏡面加 · 工後之軌道1 〇 1 a的一部分作成非爲鏡面之凹陷1 1 8，亦可 同樣的實現記號1 1 〇 F、記號1 1 0 F與記號1 1 0 B、記號1 1 0 B 等。更具體言之，係在DVD之鏡面上設以BCA形式之構 成者。 或者，如第5 ( c )圖所示，在分析用碟片1 0 8之外形一部 分上，設以凹部等形狀之異形處所1 1 9，同樣的亦可實現 記號110F、記號110F與記號110B、記號110B等。更具 體言之，使碟片之形狀作成異型，則光之反射即隨資料軌 1 道面而變化者。 分析用碟片1 〇 8中、該非爲鏡面之凹陷1 1 8、異形處所 1 1 9之詳細位置與範圍，對配置該分析對象所讀取區域1 0 9 作回轉，突係設於回轉方向之正前方位置、前後位置、正 後方位置之哪一個位置，則係與前述實施例之形態相同。 使用具有該非爲鏡面之凹陷1 1 8、異形處所1 1 9之分析 用碟片的分析裝置，其和前述各實施例形態不同之處爲其 -15- 200306413 構成係：以拾波器1 0 3讀取該非爲鏡面之凹陷丨！ 8或異形 處所1 1 9，將所檢出之記號位置用以產生各觸發信號者。 又，第5(c)圖上，分析用碟片108中之分析對象B的位 置，係與第5(a)圖之狀況相同。 (第五實施例） 上述各實施例之分析用碟片108的記號ii0F、記號hof 與記號1 1 〇 B、記號1 1 Ο B等，係以印刷、或非爲鏡面或形 狀異型等方式形成，而分析用碟片1 〇 8之凹坑、或紋道1 1 2 a 、或紋間平面1 1 2 b上，則設有該記號。 具體而言，係藉拾波器1 〇 3檢出該記號，而區別軌道資 料部分與配置該分析對象B之讀取區域1 〇 9等兩者，茲舉 下述例示說明。 屬於一種在EF Μ暨MF Μ等之凹坑處的構成者。更具體 言之，係在預設凹坑（pre-pit)、LPP (land pre-pit，紋間平 面預設凹坑MDVD-R/RW)處，於記錄位址資訊之軌道、及 與軌道間之紋間平面部上，刻以預設以凹坑者。更具體的 ，係一種CAPA(DVD-RAM之位址用的預設凹坑）等，在紋 道上或紋間平面上重疊以某些之變調者。 構成在分析用碟片1 〇 8中、凹坑或紋道或紋間平面處之 該記號的詳細位置及範圍究係位於對配置該分析對象所讀 取區域1 0 9、之回轉方向的正前方位置、前後方位置、正 後方位置等之何者位置，則均與前述各實施例之狀況相同。 使用在凹坑、或紋道、或紋間平面處形成該記號之分析 用碟片1 0 8的分析裝置，其與前述實施例之不同構成點在 -16- 200306413 於’其係以拾波器1 ο 3讀取該記號、將記號位置檢出而產 生各觸發信號者。 此外’如上述，該記號形成於凹坑、紋道或紋間平面處 ’分析用碟片108之該各記號上，於分析用碟片108中， 可將分析對象Β之配列位置或其之分析內容施以變調，使 該記號之特定圖型成爲不同之狀況時，如係使用此種分析 用碟片1 0 8時，其分析裝置之構成則如下述。 倘係使用對分析對象Β之配列位置施以特定之變調、令 該記號之特定圖型成爲不同之分析用碟片108時，分析裝 · 置之再生處理裝置107之構成，輸出：檢出拾波器103對 該記號讀取之記號位置、實施使各觸發信號補正在基準之 胃胃軸上、之圖像資料；及自所讀取記號之特定圖型的該 圖像資料、係在分析用碟片1 0 8其中一個配列位置之分析 對象Β者，之此一特定的資料，等兩者。 使用此種方式之分析裝置，例如，倘如第7圖所示之分 析用碟片的構成，可同時的實施作複數人數之血液檢查， 可對各人之檢查結果作管理。 鲁 圖示之分析用碟片1 0 8，係以記號1 1 〇 L分割爲較大的4 個領域’因之，在每個領域中即可以記號η 〇 S配置3個分 析對象Β。該等記號1 1 〇 L、1 1 〇 S係以碟片之中心作放射狀 而形成，因而形成不同之圖型，故可對分析對象Β作管理。 倘依此種方式’把不同各人之血液點著在各領域上施行 檢查時，可對4人之檢查結果作一次管理。又，倘依此種 碟片，因每個配置有3個分析對象]β，故對每個人可作3 -1 7- 200306413 次來回相同之檢查。 使用將分析對象B之分析內容施行特定之變調、令該記 號之特定圖型成爲不同之分析用碟片108的分析裝置，其 再生處理裝置1 〇 7之構成係可對應附加於：該記號由拾波 器1 0 3讀取、將檢出記號位置之各觸發信號實施補正在該 基準之時間軸上，的圖像資料；及自所讀取記號之特定圖 型、作爲目的之分析對象的種類；等之上而作管理，之後 ，則依圖像處理之內容、計數方法、判定方法等因分析對 象種類之不同而遂行自動處理。 φ 上稱之分析對象種類，如檢體爲血液之狀況，分析之項 目係指膽固醇（cholesterol)、紅血球、白血球等之分析項 目而言。因之，再生處理裝置1 0 7之構成乃爲，將該記號 之讀取記號、令該記號之位置整列於基準之時間軸上而實 行影像處理，以取得該分析對象之影像或作形狀計數，同 時，將該影像處理之結果基於該特定圖型而對應附加於該 讀取區域上以作管理，等之影像處理裝置者。 使用如第7圖所示碟片，可適用作爲上述分析裝置之分 ® 析用碟片，此種狀況，在分析用碟片之每一個領域，倘變 更分析對象之種類，以某一個人之血液、4種項目之檢查 而言，可分別實施三次之檢查管理。再者，在分析用碟片 之各領域中，亦可改變分析對象之種類，在此狀況中，一 張碟片上有複數人之血液，可實施分別作複數項目之檢查 管理。 又，第五實施例之記號1 1 〇 F、記號1 1 0 F與記號1 1 0 B、 -18- 200306413 記號1 1 0 B等，爲了考量讀取漏失，可設置複數個。f ，接近分析對象B處，依序的輪流作標識變調並記錄 藉對該等標識之讀取，即使對某一標識之讀取或有漏 亦具有補償作用之功能。 具體而言，如第8圖所示記號1 1 0 F之狀況，在分析 B之附近，分別依序置入可稱之爲等間隔” 5 "、” 4 ”、” "2 ” 1 ’’ 之記號 1 1 0 F 5、1 1 0 F 4、…1 1 0 F 1，例如，倘漏 讀取間隔” 2 ”之記號1 1 0 F 2，但之前在對” 5 ”、” 4 ”、” 3 ” 隔計數之計數時點，亦可得知間隔之規則性（rule)，故 成” 2 ”而無妨礙。如係漏失了 ” 1 ”之狀況，亦可想像爲’ 置以完成作爲影像取得觸發之機能。 又，倘利用此種方式時，係非爲線速度一定之C LV ，而光碟之回轉以C A V控制成爲一定時，亦係取得該 間隔之規則性，利用作爲同步之影像處理，如此亦可 影像。 總之，係和一般CD、DVD等之CAV讀取方式相同 用該記號之間隔以遂行檢體之影像C A V控制讀取者。 控制之狀況中，係控制碟片等之回轉爲一定者。因之 周與外周上、每個時間之移動距離即成爲不同，而對 檢體之影像取得，在一定周期取得之影像與實際之影 有所不同，爲了解決此一問題，則須變更在內周與在 上影像取得之周期，則保有和徹底的C LV控制而取得 狀況相同條件則爲必要。作爲此方法，係使該記號之 間隔以一定之間隔設置在碟片上，而與內周、外周不 如 之， 失， 對象 3丨丨， 失了 等間 可生 〇，'位 控制 記號 取得 、利 C AV ，內 每個 像乃 外周 影像 不示日哉 相干 -19- 200306413 連。作爲讀取裝置者，係使影像之讀取周期和該記號之間 隔冋步，保持此種狀況取得每一個檢體之影像。此狀況係 利用可變讀取周期之方式以配合碟片之線速度變化者。 又，前述之諸實施例係舉檢體爲血液樣本作例示，惟亦 可作其他檢體之分析使用，諸如自來水、飮料水等之分析 、貯水池等之水質分析。 又，上述各實施例之形成中，如第5圖所示，軌道1 0 1 a 係設在分析對象B之上位置或下位置處，該軌道1 〇 1 a亦 可不設在分析對象B之區間上。 以上，由第1至第5實施例可知，本發明之分析裝置暨 其所使用之分析用碟片，因爲係設置有··拾波器，係對配 置分析對象之讀取區域、在回轉方向前後位置之至少一位 置上，使用記錄有經過該讀取區域軸徑方向之區間之記號 的分析用碟片，故可檢出來自設置在該分析用碟片上之分 析對象的檢出光以及該記號；及影像處理裝置，係將追隨 軌道之拾波器在時系列上所讀取之該分析對象以及該記號 之讀取記號兩者，把該記號之位置整列於基準之時間軸以 實行影像處理，而可取得影像或作形狀處理，故可達成較 諸習用者提高分析精度之目的。 (五）圖式簡單說明： 第1圖爲本發明分析裝置第一實施例構成圖。 第2圖爲相同實施例之分析用碟片平面圖。

Pick-up (or pick-up) 1 0 3 'In the direction of the axis of the optical disc 1 (arrow A direction) Move' longitudinal feed motor (transversem 〇t 〇r) 1 0 4 The drive drives the screw_shaft 105 to rotate. The longitudinal feed motor 104 and the disc motor 102 are based on the regenerative output of the pickup 103, and the servo control circuit 6 is used to perform the following operations: The circuit 106 is based on the reproduction output of the pickup 103 and follows a groove or a groove (groove). ve) and other tracks, the longitudinal feed motor i 04 is driven in accordance with the trace method, and at the same time, the address information recorded on the disc 1 0 1 is detected and added to the disc motor 2 at a certain linear speed- 6- 200306413 is driven (CLV control). In addition, the sound signal, video signal and other data recorded on the disc are processed by the reproduction output device 107 in the reproduction processing device 107, and On the other hand, if it is the condition of the analysis device, its block is about the same as the drive of the above-mentioned optical disc. The condition of the analysis device is, as shown in Figure 10, the test sample and the test drug that cooperates with the test item The mixture of the two is set as the analysis object B. The servo control circuit 1 0 6 and the reproduction processing device 1 0 7 in the analysis device status are set on the track 1a. The optical discs are obtained as follows: An image of a part of the analysis object B. Here, the direction of the arrow on the track 1 〇 1 a indicates the tracking direction of the detected light from the pickup 103. It is also formed on the optical disc as address information. Pits, grooves, etc. Although it is used for analysis of the status of the disc, it still follows the conventional disc specifications for recording sound and video, so detailed descriptions are omitted. Here are two specific examples: Compact Disc System Despription (commonly known : Red book specification); and Compact Disc Recordable System Description (general name: Orange book benchmark). _ The laser irradiation point of the pickup 103 controlled by the servo control circuit 106 is traced to the spiral track 1 01 of the optical disc 101. The pitch of the track 1 0 1 a (for the D 1 · angeb ο κk standard disc) is 1 · 6 μ m, and the pickup 1 〇 3 is dependent on one rotation of the disc 1 0 1 The sequence is traced by 1, 2, 3 ~, 8, ... In short, as the operation of the analysis device, the part of the analysis object B and the part of the track 1 0 1 a are passed interactively and tracked. Analysis of the status of the 200306413 regeneration processing device 107 series, only extracting part of the data of the analysis object B obtained from the trace, and performing image or shape counting by reconstructing the data. In the analysis of the condition of the device, the implemented structure may be: a type that reproduces the optical disc and detects and processes the reflected light from the optical disc according to a general optical disc driving method; or it may be: detecting the transmitted light from the optical disc Type for processing; any type is acceptable. As mentioned above, the absolute time of the address information is engraved on CDs and DVDs. The time information is composed of minutes, seconds, frames, etc., and the number of frames per second is 75 frames. This time information recording method can be divided into two categories: one is to record data by changing the pit length of EF Μ, etc .; the other is: on the disc of the recording series, the texture is used as F Μ Changed into a serpentine recording. According to the general time information used by such optical discs, in the analysis device, no assembly processing or shape counting of image signals is enough to hope to improve its analysis accuracy, for the reasons described below. Either of the optical disc drive device and the analysis device, in order to retrieve an arbitrary position on the optical disc 101, the existing address information recorded on the optical disc is used. However, the minimum unit distance obtained from the address data, taking the general optical disc series as an example, its 1 second is calculated from 75 frames, and the linear velocity of the disc is greater than 1.2 m / l frames ~ 1.5 m / l frame, so it cannot be the smallest 120 (cm) T75 (frame) = 1.6 (cm) / l frame. That is, a frame whose accuracy is the smallest unit is every 16 mm. According to the current status of the analysis device for the blood test, although 200306413 is also required on a small area of about 5 mm square on the optical disc 101, it must be able to detect an accuracy of about 10 μm objects, although it has worked: The image of the analysis object B read by the track follower 1 03 in the time series is subjected to image processing, and the correct image reading result is obtained as shown in FIG. 1 (b), and the reproduction processing device ( 1 0 7) The address information is processed in the reference uplink image; and other methods, but still cannot obtain the image read as shown in Figure 11 (a). In detail, as shown in Fig. 11 (a), the reproduced image is a discontinued image that does not coincide with the position C along the disc 1 〇1 rotation direction, so it deviates from the requirements for analyzing blood, etc. The accuracy is too high. It can be understood that such an overly rough result cannot be used.

(4) Embodiments: Various embodiments of the present invention will be described below with reference to FIGS. 1 to 8. (First embodiment): FIG. 1 is an analysis device of the present invention, in which a reproduction processing device 107 composed of a microcomputer and a disc 101 replaced by the analysis disk 108 are used for analysis and are used for analysis. Different. -11- 200306413 The disc 1 08 for analysis is shown in Figure 2 on the disc! 〇 丨 A mixture of a specimen as the analysis object B and a test reagent that cooperates with the inspection item is set on the turning direction C of the reading area where the analysis object B is arranged, only at the position directly in front of it Here, a mark i10F passing through a section in the axial direction (direction of arrow A) of the read area is recorded. As shown in FIG. 2, the analysis disc 108 is provided with two analysis objects B, and the mark 1 1 0 F is formed at a position directly in front of each analysis object. In the analysis disc 108, the position of the analysis object b and the marks 1 10F of the analysis disc, etc., are configured as shown in FIG. 5. As shown in Fig. 5, the analysis target B is located between the surface 108a of the analysis disc 108 and the track 101a. The symbol 110F is printed on the inside of the optical disc 101 with ink (i n k) 1 1 1 as a strip. In Fig. 5 (a), 1 1 2 a is a pit or groove formed on the track 1 0 1 a by mirror processing. 1 1 2 b is a plane between grains (1 a n d) formed on the track 1 0 1 a by mirror processing. The analysis object B shown by the imaginary line in FIG. 5 (a) is the same as the constitution between the analysis disc 1 0 8 b and the track 1 0 1 a on the analysis disc 108. The pickup 103 traces the spiral track 1 0 1 a of the analysis disc 108, and the servo control circuit 1 06 follows the shape of the pit based on the reproduction output of the pickup 103. Or track 1 0 1 a, the longitudinal feed motor (tranversem 〇t 〇r) 1 0 4 is tracked. At the same time, the address information recorded on the track 1 〇1 a is detected to a certain extent. The linear speed drives the disc motor 102 (CLV control). The reproduction processing device 107 as an image processing device has the following configuration. -12- 200306413 Regeneration processing device 107 series. First, the image data read from the time series by the pickup 103 is stored in the memory 1 13 as tracking data. Here, since the two analysis objects B are both processed in the same way, only one analysis object B will be described with reference to FIG. 5. Figure 4 (a) shows that the optical disc 101 has one revolution, and the pickup 103 goes from the top to the bottom of the figure, and tracks from the 1st to 9th tracks are sequentially accumulated in the tracking data of the memory 11 3. Here, on the 2nd to 8th tracks, there is a part of the analysis object B at the position, and V 2 to V 8 are the decomposed image data of the analysis object B. S 1 to S 9 are signals for triggering each track position after reading the mark 1 1 OF. The trigger circuit 1 1 4 that detects the trigger signal in the tracking data read from the memory 1 1 3 and the time based on the detection output of the detection circuit 1 1 4 can correct each track data of the track The axis switching circuit 1 1 5 and the first processing unit 1 1 6 composed of the two make the output timing of the latter stage of the tracking data read from the memory 1 1 3 to delay appropriately. The positions of the trigger signals S 1 to S 9 shown in FIG. 4 (b) are in a consistent manner, and the time of each track of each track is moved to output image data D. More specifically, in the situation of Figs. 4 (a) and (b), in order to coincide with the position of the trigger signal S2, the outputs of the trigger signals S1, S3 to S9 are postponed to the latter. In this way, the track data of each track after the mark Π 0F is added to the reference time axis is accumulated in the second processing unit 1 17 and output as a reproduced image. In addition, if it is not necessary to obtain only the image of the analysis target, but the shape count (count) is required, count processing per unit area may be implemented. In this way, by arranging the position of the mark 1 1 0F on the timeline of the reference -13-200306413, according to the customary method, the address information is aligned on the timeline of the reference, and high accuracy can also be obtained. Portrait information. (Second Embodiment) Fig. 6 is an analysis disc of a second embodiment. In the first embodiment, only the reading area where the analysis object B is arranged is arranged directly in front of the turning direction, and the example shown in FIG. 6 is directly behind the analysis object B. It is also set with a mark Π 0B. In the case of the first embodiment where the mark 1 1 0B is not set, the person passing by before reaching the next reading mark 1 1 0F is recorded as a track data in the memory 1 1 3, If yes, if an analysis disc with a mark of 11 〇F is also used directly behind the analysis object B, the reproduction processing device 1 of the analysis device can be made to read from the mark 1 1 〇F to read The structure in which the trace data up to the mark 1 1 0B is accumulated in the first memory 1 1 3, and the trace data that has no relationship with the analysis target B can be accumulated without the need for processing, so that the expected high level can be achieved. Efficiency data processing. (Third embodiment) The analysis device of the first embodiment, the structure of the regeneration processing device is to read the trigger signals S 1 to S 9 after the mark 1 0F, and correct the time axis to be consistent. If the mark 1 is not set, At 1 〇F, the analysis disc 1 0 8 provided with the mark 1 1 〇B can be used only directly behind the analysis target B, and the regeneration processing device 1 007 of the analysis device can be made by: The configuration of the time axis correction of the trigger signal of the read mark 1 110B can still achieve the same expected effect as the first embodiment. In addition, in the first, second and third embodiments, the -14-200306413 shown in Fig. 2 or Fig. 6 marks 1 1 F, 1 1 0 B are offset by the center of the disc (〇ffset ), And parallel to the reading part of the analysis object B. In this case, the distance from the mark to the specimen is similar to the inner and outer phases on the disc. Therefore, when imaging a larger specimen (more than a few mm), it has undistorted and flawless imaging. Advantages. (Fourth embodiment) Any of the analysis disc 1 08, mark 1 1 0 F, mark 1 1 0 F, mark 110B, mark 110B, etc. in each of the above embodiments can be used as shown in FIG. 5 (a). It is shown that it is constructed by printing, and as shown in Figure 5 (b), a part of the track 1 01 a after mirror processing is made into a concave 1 1 8 that is not a mirror, and the same can be achieved. 1 1 〇F, symbol 1 1 0 F and symbol 1 1 0 B, symbol 1 1 0 B, and so on. More specifically, it is a structure in which a BCA format is provided on the mirror surface of a DVD. Alternatively, as shown in FIG. 5 (c), a special shaped space 1 1 9 having a concave portion or the like is provided on a part of the outer shape of the analysis disc 108, and the same can be achieved with the marks 110F, 110F, and 110B. , Mark 110B, etc. More specifically, if the shape of the disc is shaped, the reflection of light will change with the data track. In the analysis disc 1 08, the detailed position and range of the non-mirror depression 1 1 8 and the special-shaped space 1 1 9 are used to rotate the reading area 1 0 9 configured with the analysis object, and the protrusion is set in the direction of rotation Which of the forward position, the forward and backward position, and the forward and backward position is the same as that of the foregoing embodiment. An analysis device using the non-mirror-shaped depression 1 1 8 and the special-shaped space 1 1 9 is different from the foregoing embodiments in the form of the -15-200306413 composition system: the pickup 1 0 3 Read the non-mirror depression 丨! 8 or special-shaped spaces 1 1 9 are those who use the detected mark position to generate each trigger signal. In Fig. 5 (c), the position of the analysis target B in the analysis disc 108 is the same as that in Fig. 5 (a). (Fifth Embodiment) The marks ii0F, hof, and 1 1 〇B, and 1 1 〇 B, etc. of the analysis disc 108 of each of the above-mentioned embodiments are formed by printing, or non-mirror or shape irregularities. This mark is provided on the pit of the analysis disc 1 08, or the groove 1 12a, or the groove surface 1 1 2b. Specifically, the mark is detected by the pickup 103, and the track data portion is distinguished from the reading area 1109 in which the analysis target B is arranged. The following examples are used for illustration. It belongs to a kind of constructor in the pits of EF Μ and MF Μ. More specifically, it is at the pre-pit, LPP (land pre-pit, land pre-pit MDVD-R / RW), on the track where the address information is recorded, and the track On the flat part of the line between the lines, those with a preset pit are engraved. More specifically, it is a type of CAPA (a preset pit for the address of a DVD-RAM), etc., which is superimposed with some pitch on the groove or on the land plane. The detailed position and range of the mark formed on the analysis disc 1 08, the pit or the groove or the land plane are located in the positive direction of the rotation direction of the reading area 109 of the analysis target. The positions of the front position, the front and rear position, and the front and rear position are the same as those of the foregoing embodiments. An analysis device using an analysis disc 108 for forming the mark on a pit, a groove, or a plane between grooves is different from the foregoing embodiment in that the configuration point is -16-200306413 and it is used to pick up The device 1 ο 3 reads the mark, detects the position of the mark, and generates each trigger signal. In addition, as described above, the marks are formed on the pits, grooves, or land planes of the analysis disc 108, and the analysis disc 108 can arrange the analysis object B's arrangement position or other positions. When the analysis content is changed so that the specific pattern of the mark is different, if the analysis disc 108 is used, the structure of the analysis device is as follows. If a specific adjustment is applied to the arrangement position of the analysis object B, and the specific pattern of the mark becomes a different analysis disc 108, the structure of the reproduction processing device 107 of the analysis device will be output: The wave reader 103 reads the mark position of the mark, and implements the image data of the trigger stomach signal on the reference stomach and stomach; and the image data of the specific pattern of the read mark is analyzed. The analysis object B using one of the arrangement positions of the disc 108, the specific data, etc. With this type of analysis device, for example, if the structure of the analysis disc shown in Fig. 7 is used, blood tests for a plurality of people can be performed at the same time, and the test results of each person can be managed. The analysis disc 1 0 8 shown in the figure is divided into 4 large areas by the symbol 1 10 L. Therefore, in each area, 3 analysis objects B can be allocated with the symbol η 0 S. These marks 1 10 L and 1 10 S are formed by radiating the center of the disc, so that different patterns are formed, so the analysis object B can be managed. In this way, when the blood of different people is examined in various fields, the inspection results of 4 people can be managed at one time. In addition, if this type of disc is used, since there are 3 analysis objects] β in each configuration, each person can perform the same inspection for 3 -1 7- 200306413 times. An analysis device that performs a specific change of the analysis content of the analysis object B to make the specific pattern of the mark into a different analysis disc 108, and the reproduction processing device 1 07 can be correspondingly added to: The pickup 103 reads and corrects each trigger signal of the detected mark position on the time axis of the reference, image data; and the specific pattern of the read mark as a target analysis object Type; etc. for management, after that, it will be automatically processed according to the type of analysis object, depending on the content of image processing, counting method, and determination method. φ The type of analysis object mentioned above, such as the condition of the specimen as blood, the analysis items refer to the analysis items of cholesterol (cholesterol), red blood cells, and white blood cells. Therefore, the structure of the reproduction processing device 107 is to perform image processing by reading the mark of the mark and aligning the position of the mark on the reference time axis to obtain the image of the analysis object or to count the shape. At the same time, based on the specific pattern, the result of the image processing corresponds to an image processing device that is attached to the reading area for management, and so on. The disc shown in Figure 7 can be used as the analysis device of the above-mentioned analysis discs. In this situation, in each area of the analysis discs, if the type of analysis object is changed, the blood of a certain person is used. For the inspection of four types of projects, three inspection managements can be implemented respectively. In addition, in each area of the analysis disc, the type of analysis object can be changed. In this case, there is blood of a plurality of persons on one disc, and inspection management of each item can be implemented. In addition, in the fifth embodiment, a plurality of symbols 1 1 0 F, 1 1 0 F and 1 1 0 B, -18-200306413, 1 1 0 B, etc. may be provided in order to consider the missing reading. f, close to the analysis object B, and sequentially change the marks and record them in turn. By reading these marks, even if there is a reading or omission of a mark, it has the function of compensating. Specifically, as shown in FIG. 8, the condition of the symbol 1 1 0 F is placed in the vicinity of analysis B, which can be called equal intervals “5 ",“ 4 ”,“ " 2 ”1 "1 1 0 F 5, 1 1 0 F 4, ... 1 1 0 F 1, for example, if the reading interval" 2 "is missed 1 1 0 F 2, but the previous" 5 "," 4 ”,“ 3 ”When counting the interval, you can also know the regularity of the interval (rule), so it becomes“ 2 ”without hindrance. If you miss the situation of“ 1 ”, you can also imagine it as' set to Complete the function of triggering the image acquisition. In addition, if this method is used, it is not a C LV with a constant linear speed, and when the disc rotation becomes constant with CAV control, the regularity of the interval is also obtained and used as synchronization In this way, it can also be used for image processing. In short, it is the same as the general CAV reading method of CDs, DVDs, etc. The reader is controlled by the image CAV of the specimen at the interval of the mark. In the control situation, the disc is controlled The turn of waiting is constant. Because of this, the moving distance of each time on the periphery and the periphery becomes different. For the acquisition of specimen images, the images acquired in a certain period are different from the actual images. In order to solve this problem, you must change the period between the inner periphery and the previous image acquisition, and maintain a thorough C LV It is necessary to obtain the same conditions under control. As this method, the interval between the marks is set on the disc at a certain interval, and it is not as good as the inner and outer peripheries. It can generate 0, 'bit control mark acquisition, benefit CAV, each image is a peripheral image without showing sundial coherence -19- 200306413. As a reading device, the reading cycle of the image and the interval between the marks Step by step, keep this situation to obtain an image of each specimen. This situation is to use a variable reading cycle to match the linear speed of the disc. In addition, the foregoing embodiments are based on the specimen as a blood sample As an example, it can also be used for the analysis of other specimens, such as the analysis of tap water, raw water, etc., and the water quality analysis of storage tanks. In addition, in the formation of the above embodiments, as shown in FIG. 1 0 1 a is located above or below the analysis object B, and the track 1 〇 1 a may not be located on the interval of the analysis object B. As described above, according to the first to fifth embodiments, The analysis device and the analysis discs used by it are equipped with a pickup. They are used to read the reading area where the analysis object is arranged and at least one of the forward and backward positions in the direction of rotation. Discs for analyzing the marks in the area of the axis direction of the area, so it can detect the detection light from the analysis object set on the analysis disc and the marks; and the image processing device will follow the pickup of the track Both the analysis object read by the time series and the reading mark of the mark, the position of the mark is aligned on the reference time axis to implement image processing, and the image or shape processing can be obtained, so it can be achieved The purpose of improving the accuracy of analysis compared to users.
